APPARATUS FOR CONTROLLING THE SPEED OF MOTOR-CAR ENGINES.

SPECIFICATION forming part of Iletters Patent No. 757,815, dated April 19, 1904.

Application filed May 8, 1903. Serial No. 156,314- (No model.)

To all whom it may concern:

Be it known that I, ARTHUR KREBS, engi neer, a citizen of the French Republic, residing at Paris, department of the Seine, France, (having post-office address 19 Avenue dIvry, in said city,) have invented certain new and useful Improvements in Apparatus for Controlling the Speed of Motor-Car Engines, of which the following is a specification.

My invention relates to improvements in apparatus for controlling the speed of motorcar engines.

In order to control the speed of an internalexplosion motor, itis necessary to either regulate the admission of the explosive mixture to the cylinder or the exhaust or to regulate the time at which the explosion is to take place.

According to my invention I provide an apparatus by the use of which the admission, the exhaust, or the ignition, as the case may be, may be controlled by the turning of a thumb-screw or similar device mounted on the steering-wheel of the motor-car, thus obviating the necessity for the driver to take his attention from the road, as has heretofore been necessary when the means of manipulation of the apparatus for controlling the speed of the motor have been placed in other positions on the car.

In the accompanying drawings I have illustrated how my invention may be carried into practice.

Figures 1 and 1" taken together show a longitudinal section of my apparatus applied to the steering-wheel of a motor-car. Figs. 2 and 2 taken together show a part of the steering-wheel with my improved apparatus secured thereto; and Fig. 3 is a cross-section of the apparatus, showing the winding-drums g with the cords A attached thereto.

According to my invention I provide on the steering-wheel a fixed shaft a, arranged diametrically and secured thereto at its ends on and n in any convenient manner. The shaft (0 is also secured to the steering-pillar by means of a cylindrical cap I). This cylindrical cap L is provided on its ends with notches the end of each sleeve is a thumb-screw la,

similarly secured. Each sleeve 0 also carries a revolving drum 9, to which the ends of the chains, cords, or cables ii are secured, the

other ends of the said cables being connected With the inlet-valve or the apparatus for timing the ignition or other part of the apparatus used for regulating the speed of the engine.

The cables preferably traverse the steeringpillar and from thence are conveyed in any convenient manner to the apparatus with which they are to be connected.

In the case Where one cable is connected with the inlet-valve and the other with the apparatus for timing the ignition the driver is able to control either the admission of explosive mixture or the timing of the ignition by turning one or both of the thumb-screws A, as the case may bethat is to say, if he Wishes to change the position of the admission-valve he turns one thumb-screw, and if he wishes to change the timing of the ignition he turns the other thumb-screw. The turning of either of the thumb-screws'assures the turning of the drum it is connected with, as above described, and the maintenance of the entire apparatus in any determined position is assured by the engagement of the notches, which engagement is rendered positive by means of the spring 6. The thumbscrews may be turned by the driver in either direction by first pressing them outward against the action of the spring.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed. I declare that what I claim is 1. An apparatus for controlling the speed of motor-car engines, comprising a steeringwheel, a shaft extending transversely of said wheel, means rotatably mounted on said shaft, and means connected with said rotatable means and with the speed-regulating means of the engine for controlling the speed of the engine when said first means is rotated.
